[Thésaurus Mesh]PiedMots-clés : arc artériel plantaire profond amputations transmétatarsiennes Résumé : Background: The deep plantar arterial arch (DPAA) is formed by an anastomosis between the deep plantar artery and the lateral plantar artery. The potential risk of injury to the DPAA is concerning when performing transmetatarsal amputations, and care must be taken to preserve the anatomy. We sought to determine the positional anatomy of the DPAA based on anatomical landmarks that could be easily identified and palpated during transmetatarsal amputation.
Methods: In an effort to improve our understanding of the positional relationship of the DPAA to the distal metatarsal parabola, dissections were performed on 45 cadaveric feet to measure the location of the DPAA with respect to the distal metatarsal epiphyses. Images of the dissected specimens were digitally acquired and saved for measurement using in-house–written software. The mean, SD, SEM, and 95% confidence interval were calculated for all of the measurement parameters and are reported on pooled data and by sex. An independent-samples t test was used to assess for sex differences. Interrater reliability of the measurements was estimated using the intraclass correlation coefficient.
Results: The origin of the DPAA was located a mean ± SD of 35.6 ± 3.9 mm (95% confidence interval, 34.5–36.8 mm) proximal to the perpendicular line connecting the first and fifth metatarsal heads. The average interrater reliability across all of the measurements was 0.921.
Conclusions: This study provides the positional relationship of the DPAA with respect to the distal metatarsal parabola. This method is easily reproducible and may assist the foot and ankle surgeon with surgical planning and approach when performing partial pedal amputation.Permalink : https://bibliotheque.helb-prigogine.be/opac_css/index.php?lvl=notice_display&id= [article]Exemplaires

[Thésaurus Mesh]Traumatismes du piedRésumé : Background
The deep plantar (D-PL) artery originates from the dorsalis pedis artery in the proximal first intermetatarsal space, an area where many procedures are performed to address deformity, traumatic injury, and infection. The potential risk of injury to the D-PL artery is concerning. The D-PL artery provides vascular contribution to the base of the first metatarsal and forms the D-PL arterial arch with the lateral plantar artery.
Methods
In an effort to improve our understanding of the positional relationship of the D-PL artery to the first metatarsal, dissections were performed on 43 embalmed cadaver feet to measure the location of the D-PL artery with respect to the base of the first metatarsal. Digital images of the dissected specimens were acquired and saved for measurement using in-house software. Means, standard deviations, and 95% confidence intervals (CIs) were calculated for all of the measurement parameters.
Results
We found that the origin of the D-PL artery was located at a mean ± SD of 11.5 ± 3.9 mm (95% CI, 4.5–24.7 mm) distal to the first metatarsal base and 18.6% ± 6.5% (95% CI, 8.1%–43.4%) of length in reference to the proximal base. The average interrater reliability across all of the measurements was 0.945.
Conclusions
This study helps clarify the anatomical location of the D-PL artery by providing parameters to aid the surgeon when performing procedures in the proximal first intermetatarsal space. Care must be taken when performing procedures in the region to avoid unintended vascular injury to the D-PL artery.Permalink : https://bibliotheque.helb-prigogine.be/opac_css/index.php?lvl=notice_display&id= [article]Exemplaires

[Thésaurus Mesh]Statistiques comme sujetRésumé : Background: Direct assessment of health professional student performance of clinical skills can be accurately performed in the standardized performance assessment laboratory (SPAL), typically by health professional faculty. However, owing to time and economic considerations, nonmedical individuals have been specially trained to perform the same function (standardized patients [SPs]). This study compared the assessment scores of the history and physical examination components of a SPAL designed for second-year podiatric medical students at Des Moines University (DMU) by a podiatry medical faculty member and SPs.
Methods: A total of 101 students from the classes of 2015 and 2016 were evaluated in 2013 and 2014 by 11 to 13 SPs from the DMU SPAL program. The video recordings of these 101 students were then evaluated by one faculty member from the College of Podiatric Medicine and Surgery at DMU.
Results: The Pearson correlation coefficient for each class showed a strong linear relationship between SP and faculty assessment scores. The associations between SP and faculty assessment scores in the history, physical examination, and combined history and physical examination components for the 2016 class (0.706, 0.925, and 0.911, respectively) were found to be stronger than those for the 2015 class (0.697, 0.791, and 0.791, respectively).
Conclusions: This study indicated that there are strong associations between the assessment scores of trained SPs and faculty for the history, physical examination, and combined history and physical examination components of second-year SPAL activity for podiatric medical students.Note de contenu : Article original Permalink : https://bibliotheque.helb-prigogine.be/opac_css/index.php?lvl=notice_display&id= [article]Exemplaires
